How about a personalized birdhouse? You could get one with his name on it and choose a design that features his favorite type of bird. You could even fill it with birdseed as an extra gift. Alternatively, you could get him a birdwatching book or guide so that he can learn more about the birds he likes. Finally, you could get him tickets to a bird sanctuary or bird-watching trip so that he can see them up close in their natural habitat.
Or you can get him a star map with the date of your anniversary.
